NVIDIASkill

trtllm-test-specialist

NVIDIA/TensorRT-LLM/.claude/skills/trtllm-test-specialist/SKILL.md

Model tests are further classified by type (functionality/smoke test, benchmark, or evaluation). Prompts the user for parallelism parameters (tp, ep, dp), dataset paths, device type, or a config file as needed. All test execution is delegated to trtllm-case-executor.

omnigent-aiSkill

run-load-test

omnigent-ai/omnigent/.claude/skills/run-load-test/SKILL.md

Run the Omnigent load test and produce a results file explaining the latencies. Load when the user wants to load-test / stress-test / benchmark Omnigent under concurrency ("load test omnigent", "stress test the server", "how many hosts/sessions/turns can it handle", "load test real agent turns / conversations", "run a load test"). The test makes each simulated user a real omnigent host that creates host-bound sessions and drives real multi-turn conversations with a mocked LLM; it boots its own local stack (dev/loadtest/run.py). Gather inputs, run it, then read the generated summary.md and explain the latency distribution (avg/median/p95/p99, throughput, failures). NOT for single-request latency micro-benchmarks (that is dev/benchmarks/).

PostHogSkill

maintaining-python-tests

PostHog/posthog/.agents/skills/maintaining-python-tests/SKILL.md

Maintains existing pytest and Django test suites without weakening correctness. Use when asked to reduce Python test runtime or CI work, investigate slow pytest families, remove stale migration tests, consolidate repeated setup, improve Python test ownership, or measure whether a test optimization worked after merge. Ranks work by measured cost, applies the writing-tests value gate to existing coverage, preserves distinct behavior cases, validates isolation after shared-fixture changes, and separates testcase work from pytest-suite wall time. For an intermittent failure, use fixing-flaky-tests instead.

CLAUDE.md vs AGENTS.md

About skills

What is a Claude skill?

A folder with a SKILL.md file: a name, a description of when to use it, and instructions. Claude loads a skill only when the task matches its description.

How do I use one I find here?

Copy the folder into your project's .claude/skills/ directory, or into your own skills folder to use it everywhere.

What do the warnings mean?

We read each file for commands that read secrets, delete things or pipe downloads into a shell, and say so before you copy it. No warning is not a promise that a file is safe.

Which skills worked for people?

Open a skill to see its discussion. Reports from people and their agents are coming.
